XPath extension functions 2003-05-16 - By CANDAT Jerome
Hello everyone,
First I will say that I'm totally new to Xalan.
Here is my question.
In fact, I would like to use Xalan only for its Xpath capabilities.
I have an XML file and would like to use the Xpath functions to 'query' this
document without using any XSL capabilities (so without any stylesheet). I just
to use the Xalan XPath API from myu own Java code.
I don't think it should be a problem ???
However, in my case, I need to have an ends-with() functions. As it does not
exist in the XPath specification I assume it does not exist in Xalan either (I
may be wrong since I haven't used Xalan yet but I read many times that Xalan
followed the W3C specs,so..).
More, I've read on the Xalan web-site that it was possible to extend the core
library of functions that XPath provides.
I was wondering if it was possible to 'declare' my ends-with() function and use
it in my XPath expression using the Xalan Xpath APIs as well as if it was a
native function (like for example /doc/param[ends-with(@(protected),'lan')]) ?
Thanks in advance,
Jérôme.
